SHUTTLE-CHANGING MECHANlSM FOR LOOMS.

v SPECIFICATION forming partof Letters Patent No. 633,952, dated September 26, 1899.

Application filed ne 24, 1897. Serial No. 642,078. (No modeli To all whom it may concern: I

Be it known that I, EMIL CLAVIEZ, a, citizen of the German Empire, residing at Leipsic, Germany, have invented certain new and useful Improvements in Shuttle-Changing Mechanism for Looms, of which the following is a specification.

The invention relates to shuttle-changin g mechanism for looms in which a vertical row of separate shuttles is arranged in front of the lay and is supported on a fixed table so that the bottom shuttle may be called into action whenever a change of color is to be made. When the shuttles are to be changed,- the lowermost of the vertical row of shuttles is pushed along the table into the advancing lay after a previous shuttle has been removed The mechanisms for removing the old and inserting the new shuttle are set in action either by an electromagnet or by purely mechanical means.

In the accompanying drawings, Figure 1 is a side elevation of a loom, showing the shuttle-changing mechanism. Fig.2 is a rear' elevation of part of the loom, showing said changing mechanism from the left-of Fig. 1. Fig. 3 is a plan view of the said mechanism. Figs l to 7 are diagrammatic views illustrating the manner of ejecting the old and inserting the new shuttle. Figs. 8 to 10 show the main working parts in various working positions. Figs. 11 and 12 show an electromagnet for determining the time when the change of shuttle is to occur.

Similar letters of reference indicate corresponding parts.

The loom maybe of any preferred construction,consisting of the frame, lay, heddles, &c. which are not necessary to be herein particularly illustrated 0r described, but which are sufliciently illustrated and described so as to I enable persons skilled in the art of weaving to adapt the present improvements thereto.

The working shaft of the loom carries a cam E,which through the medium of a link G,which has an antifriction-roller arranged in the camgroove of the cam E, oscillates a lever H, which is fulcrumed atits lower end at L at a suitable point on the frame of the machine, and said lever H has pivoted to its upper end a pawl K, the tooth of which is adapted to engage with a projection 11, extending in the opposite direction from a latch F, which is pivoted tolthe upper end of said lever H,abovethetension of a spring, said lever being op erated by means of a cord 0, guided over a suitable pulley on the frame and attached at its lower end to a lever H pivoted at n to thelower portion of the frame of the machine. This lever H has a pin-and-slot connection (1-, as shown clearly in Figs. 1 and 9, with the elbow-lever H of a second lever H, which is pivoted at its lower end at Z to the frame of the machine. S is an upright rod which carries' at its upper end a plate EV, to be hereinafter particularly described. The said lever H is provided with "a pin a, over which the hook endow of the latch F, which is pivoted to the lever H, is adapted to engage, while on the other hand the lever H is provided with a pawl k", the hook end of which is adapted to engage a projection R on the lay. (See Figs. 9 and 10.)

. Arranged at the upper forward portion of the frame of the loom is a fixed table T, upon whichslides a push-wall to, which is operated by the upper end of said oscillating lever H. The shuttle holding or collecting box B is arranged in upright position above the table T and contains a vertical row or tier of shuttles, which are to be transferred one by one to the lay. Arranged parallel with the pushwall to is the aforesaid front wall W, which is carried at the upper end of the verticallymovable rod S, while arranged parallel with the front wall W is a rear wall A, which is pivoted at 2'. to a suitable point of the lay. I

The main working parts of the shuttlechanging mechanism having been briefly outlined, the operation of the same will now be these the shuttle-box walls on the change side are formed by the front wall \V and the rear wall A, while the wall in is movable forward and backward toward the lay on the fixed table T, arranged in front thereof under the shuttle collecting box. (See particularly Figs. 4: to 7.) By the term change sidein the present invention is intended that side on which the improved shuttle changing mechanism itself is located, and the front wall 7 and the rear wall A are in particular meant thereby for the reason that the changing of the shuttles is brought aboutthrough the influence of the three movable walls, one of which, 1U,'1I10V6S under the shuttle-box B. When the change is to be elfected, the inner end of the rear wallAis moved into the box, Figs. 3 and 4. Consequently the shuttle coming from the other side slides under the inclined wall A and is conveyed out of the lay onto a suitable incline, which delivers it into a collecting-receptacle at the disposal of the weaver. On the succeeding forward movement of the lay the front wall WV rises, and push-wall w by the movement toward the lay pushes the lower shuttle of the vertical row of shuttles from the table T into the lay, Figs. 1 and 5. The inserted shuttle then forces the rear wall A into its original position parallel with the walls W and 'w. The walls 1V and to follow the shuttle backward .and form the front wall of the shuttle-box until the shuttle movement, Fig. 6,t-akes place. The wall to then returns to the table T, whereupon the main-shuttle front wall WV returns backward into its former position. (Shown in Fig. 4:.) If the wall 10 in its return movement moves far enough to the right, a new shuttle will fall downward from the receptacle B, Fig. 7. As the insertion of a new shuttle in the lay now immediately takes place, it is possible to change both shuttles with one change. These movements of the walls A, V, an d w are carried out through the medium of the instrulnentalities above described,as follows: \Vhen it is desired to change the shuttles, a current from a suitable source of electricity and in connection with such a pattern .mechanism as is fully shown and described in my Patent No. 572,245, dated December 1, 1896, is caused to pass through the coils of the electromagnet M, so that its armature m is drawn toward the same to the left, as shown in Figs. 2 and 11. The projection g at the upper end of the armature m is thus brought into the path of a trip-lever F, which is pivoted to the lay at a suitable point, as 8, above the electromagnet and which is at this time moving backward with the lay, which trip-lever, consequently, encountering the said projection g, rocks on its pivot s and through the medium of its projection s raises an arm 25', (see Fig. 12,) so as to operate a latch N, which is also pivoted to the lay near the free end of the rear wall A. This latch N is, by means of a spring it, forced upwardly, so that its tooth or is caused to engage with the free end of said rear wall A, when the same has been forced into position parallel with the front wall W by the insertion of a new shuttle. By the pushing up of the arm 25 the latch N is released from the movable end of the hinged rear \vallA, so that the same, under the action of its spring 70, is moved on its pivot 2' into oblique position relatively to the shuttle-box, so that the shuttle coming from the other side will slide along the back of the said wall and be thus removed from the lay. On the subsequent forward movementof the lay the pawl K of the lever H encounters the lower projection h on the armature m and is then drawn to the left, Fig. 8, so that the said pawl K is thereby held back and releases the latch F, which was previously engaged by the tooth of the pawl. The latch F now drops and engages by its outer hook end acthe pin a on the lever H and draws this lever onto the lay on the return of the said lever H. The lever H is thereby caused to push the wall w along the table T, whereby the lowermost shuttle is forced from said table into the lay. Just before this movement, however, the shuttlewall 1V must be raised, and to this end the lever H, by means of its elbow projection H during its movement to the rear, raises the lever H Figs. 1 and 9, whereby the upright rod S is moved upwardly so as to push up the front wall XV. In order that the push-wall w may remain on the lay during the pushing oil of the shuttle and may form the front wall of the shuttle-box, the pawl K, carried by the lever H, is caused to engage with the projection R on the lay, so that the lever H and the wall 10 must move together to the rear with the lay. The extent to which the said lever H is carried backward by the lay is limited by a link Z, pivoted at its up per end to the forwardly-projecting portion of the pawl K and at its lower end having a slotted frame or head 0, which is guided on an adjustable bolt y, arranged on the frame of the loom. By this means at the proper moment the hook of the said pawl K is lifted and disengaged from the projection R, where upon a tension-spring f, or its equivalent, draws the lever H again to the front, while the levers H H and the rod S lower the front wall W. The lifting of the latch F takes place when the pin a on the lever H encounters the bulgeor projection gon the latch F, the latter being raised so far that the tooth of the pawl K under the action of its spring f can again engage the projection of said latch and hold the same in raised position until it is again released by said pawl.

Having thus described myinvention, what I claim is- 1. In a shuttle-changing mechanism for looms, the combination, witha collecting-box, a table below said box, a push-wall guided along said table, a horizontally-movable rear wall on the lay, and a vertically-movable front wall, of means for moving the rear wall and push-wall away from the collecting-box, along position relatively to the lay, and means for holding the said pivoted rear Wall retracted, against the force of said spring, of a vertically-movable front Wall, means for moving the front Wall, a push-wall guided on the said table, below the collecting-box, and means for moving said push-wall, substantially as set 20 forth.
